Change first priority to "Buildings" if enemies are near buildings, and "City Wall" if enemies are near the cities wall.The settings used for decoys are usually that of the first. As for the settings of other troops, it is case-to-case basis. Just ask around.

There are times in which we set out on a chain of attacks and you troop don't get to return to you manors. Thus, to resupply them with troops and food, you need the following.a. A hero with wagons to bring food to the latest acquired city.b. A hero to bring the newborn troops to the latest acquired city.

As mentioned earlier, food are needed to move units around and it often adds up to a large amount. As your main troop fight further away from your troop manor, the issue is back again. Thus, to minimize such wastage, we suggest that the troop manor should be abandon once in a while and shifted closer to the war front.
